Replaceable tire tread belt and tire carcass with a buttressed sidewall

ABSTRACT

a replaceable tire tread belt has radially outer and inner peripheral surfaces and a pair of opposite side surfaces defining a preselected axial width. The tread belt is mounted on a tire carcass having a radially outer peripheral portion, a facing pair of sidewalls, and a radially inner base portion. A buttressed deflector of preselected cross sectional configuration extends axially outwardly from at least one sidewall of the tire carcass a distance axially beyond the tread belt of from 5 to 71/2% of the preselected axial width for deflecting external objects away from the sidewall.
